AI Engineer · Applied AI & agent systems
I build products, automations and tools with AI agents. Based in São Paulo, Brazil, I work on applied AI at NexUnio and publish the tools I build for my own workflow.
My day-to-day work combines problem definition, agent orchestration, integrations and product validation. I coordinate agents for implementation and independent review, test the resulting behavior and iterate until the product works. Recent work centers on reliable AI assistants, evaluation workflows and tools for running multiple agents.
| Activity | Recorded figure |
|---|---|
| GitHub contributions | 11k+ in the last 12 months, including private repositories; checked September 11, 2026 |
| Cumulative AI token usage | 161.9 billion estimated, across Codex/GPT, Claude Code and Grok; recorded September 8, 2026 |
The token estimate combines usage-panel records and my own notes: 96.9B Codex/GPT + 45B Claude Code + 20B Grok. It describes cumulative usage across tools, not a weekly total or generated output alone. Usage record and projects →
At NexUnio, I work on:
- NexSales — AI customer-service agents with tool integrations, conversation evaluations, versioned rules and human handoff.
- NexARQ — a platform for architecture firms, combining web, mobile, business workflows and applied AI.
- SFR Resgate Digital — a mobile app for pre-hospital rescue workflows, with offline forms and synchronization.
I also build DailyWork, my private workspace for collecting agent-session history, organizing evidence and tracking what I ship. Selected work appears on lucas-ol.com.
